In Nietzsche’s notion of “eternal recurrence,” “noble” spirits and the master race would again experience the triumph of the will in the cyclical swings of history. Yet, eternal recurrence, meant a lack of overall progress, so that the cumulative result was “Nothingness (the ‘meaninglessness’) for ever more!” Although Nietzsche wished to supersede nihilism through the Overman as the personification of the will-to-power, it was to nihilism that everything always eternally returned, as genuine forward progress was foreclosed.

I think this is part of what powers a certain toxic nostalgia.
